555 timer oscilloscope measurements

I’m using a Tenma 30v /3A bench power supply
Just connected to live and neutral outputs at 5v setting
Guessing that hooking onto 0v on my breadboard gives me my reference base

A suggestion: Do not use "live" and "neutral" for the outputs of a power supply. Those terms are pretty much exclusively used for mains power.
If you use them for power supply outputs, many people are going to think "mains" and go into "protect the newbie" mode, giving you all sorts of warnings that aren't going to make sense.
Brumby:
If you are new to scopes, then this is worth watching (pretty much a standard recommendation, in fact)...

yep ok I mean 0v and 5v low voltage supply
Brumby:
:-+ That's much better. Everyone will understand that immediately.
